SPECIFICATION forming part of Letters Patent No. 7295371, dated May 26,1903.

Application iiled January 31, 1903. Serial No. 141,282. (No model.)

To a/ZZ whom, it muy concern."

Be it known that I, EDWARD G. LUTZ, a `citizen of the United States ofAmerica,residing at Avalon, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMet-al Shoe-Soles, of which the following is a specification, referencebeing had therein to the accompanying drawings. Y

This invention relates to certain new and useful improvements in metalsoles for shoes, and relates more particularly to that class of shoeswhich are'used in mill work'and the like.

The object of the invention is to provide a metal sole which may beapplied to any shoe for the purpose of permitting the metal sole to beremoved when the same is not required for actual use, therebypermitting` the wearing of a lighter and more comfortable shoe.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this speciiication, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which- Figure l is a perspective view of the under side of ashoe with my invention applied thereto. Fig. 2 Vis a centralcross-section taken at the hinge of the metal sole. Fig. 3 is afragmentary sidevelevation showing means for securing the rear end ofsaid sole to the shoe. Fig. 4 is a side elevation of this device appliedto a shoe, a modified form of means for holding the same thereto beingillustrated.v Fig. 5 isa face View of said means for holding the sole tothe shoe..

In the drawings the reference-numerafl indicates the forward part ofthis metallic sole,which is provided with cut-away portions 2 2 for thepurpose of decreasing the Weight, the strips which are formedbetween thesaid cut-away portions having secured thereto or formed integraltherewith numerous hobs or projections 8, which take the place of thehobnails in the ordinary shoe. At the forward ends and sides of thispart l are formed clamp-pieces 4, which are adapted to engage the sidesand top edge of the sole in the 5o manner similar to that which has beenused lion skates, (Sac. The rear end of this part l has lugs 5 bent upin a similar manner to the clamp-pieces 4, but forkthepurpose of forminga pivotal connection between said part l and the part 6. At a suitablepoint forward of the heel there is secured to the sole of the shoe aplate J7, provided with a notched block 8, and at the rear ends of thepart 6 there are provided tongue-pieces 9, which V'are adapted to beinserted under the forward end of the plate 7 Thesaid pieces l and. 6will be retained in this position by the connection of the spring 10,which is pivoted in the lugs 1l on the part (3, the rear end of which isin the form of a yoke and which engages the notches in the block S onVplate 7. This spring is so arranged that it normally engages saidnotches, and when it is desired to remove this metal sole the spring iswithdrawn from the notches by pulling the loop'l2 away from the block 8,thereby freeing the metal sole.

It will be noted that by inserting the rear end of the piece (i underthe forward ends of the piece 7, which is secured to Athe sole of theshoe, piece 6 is held normally in place and there is not opportunity forthe same to become disengaged from the shoe. y

A modified form of securing the rear end of the piece 6' to the sole ofthe shoe is shown in Figs. 4 Yand 5, and'it consists in providing `therear end of piece v6' with a yoke or loop l13, which is engaged by thespring-pressed lever 14. This lever 14 is either held in the `open orclosed position by 'the action of the release-spring l5 on the iiattenedportion of the bearing of said lever.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is'- y l. A device of the type setforthcomprising in combination with" a sectional sole means carried onthe forwardp'ortion" of'the sole for engagement with the shoe, lockingmeans pivotally mounted on the rear portion of the sole, said rearportion-having rear,- wardly-extending projections, a clampingplateadapted to receive said extensions, and

a rack member carried thereby for engagement with the locking means onthe rear portion of the sole, substantially as described.
